An AR-15 side charging bolt carrier group is a piece of a firearm that houses many key parts such as the firing pin, gas key, cam pin, extractor, and bolt. With all these pieces working together the BCG can grab and feed another round out of the detachable magazine chamber. During the extraction of a cartridge, the BCG works to absorb the force of the explosion by expanding gas in the carrier. Throughout this process, gas is tapped off from the barrel and sent into the cup inside of the gas key which creates an inertial force that sends the Bolt Carrier Group back into the buffer tube. This entire process helps to reduce recoil.
Upper Receivers mount and house the barrel, handguard, and gas system in a AR-15 or LR-308/AR-10. Custom upper receivers vary from Side Chargers, and Skeletonized uppers, to Rigidity Reinforced or 'Lite' receivers, where certain features such as the forward assist and brass deflector are removed to streamline the design. This also applies to most Pistol Caliber Carbine upper receivers with special ejection door cuts made specific for 9mm or .45ACP.
